The mPulse Believe is Sunlighten’s two-person Intelligent Infrared Sauna. Its PulseIQ™ platform separates and independently controls red light plus near-, mid-, and far-infrared, providing a more personalized experience than conventional blended full-spectrum systems.

An in-sauna smart tablet offers built-in wellness programs and customized session controls. The Sunlighten app adds remote start, scheduling, and session management. With comfortable seating for two and your choice of Basswood or Eucalyptus, Believe is well suited for couples, shared wellness routines, or individuals who prefer additional interior space.

Electrical Requirements

• Electrical supply: 120V

• Required outlet: NEMA 5-20
• Power cord: Approximately 10 feet

The Believe must plug directly into its dedicated wall outlet. Do not use a power strip, extension cord, converter, or plug adapter. The circuit and receptacle should be installed and verified by a licensed electrician in accordance with applicable local codes.

Placement Requirements

• Install on a smooth, level, dry, and stable surface.
• Allow at least 4" between the sauna and surrounding walls.
• Allow at least 6" above the sauna.
• Maintain access to the electrical outlet and circuit reset.
• Keep the sauna away from plumbing, standing water, excessive moisture, combustible materials, and corrosive chemicals.
• Confirm that Wi-Fi coverage reaches the sauna location.
• Measure the complete pathway to the final installation room before ordering.

Sunlighten saunas are designed primarily for protected indoor installation. Outdoor placement requires the correctly sized Sunlighten sauna cover and full compliance with the manufacturer’s instructions. Installing the sauna outdoors without an approved cover may void warranty coverage.

In-stock Sunlighten saunas normally leave the manufacturer in approximately 3–5 business days. Freight transit may take an additional 12–15 days to reach the customer’s local area. The local freight carrier will contact the customer to arrange a delivery appointment.

The Believe arrives palletized in two large cartons. Delivery requires a flat, paved access area extending to the garage or designated delivery point. Standard freight carriers do not transport the cartons up steps or assemble the sauna inside the home.

Before delivery:

• Confirm that the carrier has the correct phone number.
• Clear a flat, paved area for the pallet.
• Measure the entire route to the installation room.
• Confirm that the 56" × 17.5" × 76" wall carton will fit through the pathway.
• Arrange for at least two capable adults to move and assemble the panels.
• Have the dedicated 120V, 20-amp receptacle installed and tested.

Inspect all cartons before signing the delivery receipt. Note punctures, crushing, tears, moisture, missing cartons, or other visible damage on the delivery paperwork and take photographs. Contact Core Human Health immediately if shipping damage is discovered.

Transit times are estimates and may vary based on inventory, customer location, weather, carrier capacity, and delivery accessibility.

Routine Care

• Dry the interior after every session.

• Do not use bleach, harsh chemicals, abrasive cleaners, or heavily scented products on the interior wood.
• Clean heater fabric only when the sauna is turned off and cool, using a lightly dampened cloth with clear water.
